PVC-U and PVC-M pressure pipes are suitable for use at service temperatures up to 50Â°C. For PVC-O pipes, the maximum continuous operating temperature should be limited to 45Â°C.
1 In a solar cell, the parameter most affected by an increase in temperature is the open-circuit voltage. 2  As the temperature increases, the open-circuit voltage decreases, thereby decreasing the fill factor and finally decreasing the efficiency of a solar cell.3  It is recommended to operate at 25 degree celsius. In addition to reflecting the performance of the solar cell itself, the efficiency depends on the spectrum and intensity of the incident sunlight and the temperature of the solar cell. 2  The efficiency of a solar cell is determined as the fraction of incident power, which is converted to electricity and is defined as:
